# KOL Discovery

Cross-platform influencer and creator discovery through SandBase. Find, evaluate, and compare creators across TikTok, Instagram, YouTube, and Xiaohongshu. Read [the API map](references/sandbase-api-map.md) before selecting a capability.

## Call SandBase capabilities

For every selected tool, call `sandbase_describe_tool` first and use only arguments in its current input schema. Then call `sandbase_call_tool` with the exact `tool_name`.

## Operating principles

- Evaluate creators by engagement rate, not just follower count.
- Cross-platform presence indicates established creators.
- Engagement rate = (likes + comments) / followers for each platform.
- Focus on content relevance and audience fit, not vanity metrics.
- Respect creator privacy — only report on public information.
